The world of desktop computing has coalesced into what is essentially a duopoly, with Windows machines making up the bulk of the market share and Apple carving out a dedicated minority. This relatively stable state hasn’t always existed, though, as the computing scene even as late as the 90s was awash with all kinds of competing operating systems and various incompatible hardware. Amiga, Unix, OS/2, MacOS, NeXT, BeOS, as well as competing DOSes, were all on the table at various points.
If you’ve still got a box running one of these retro systems, SheepShaver might be able to help expand your software library. It’s not the sort of virtualization that we’re used to in the modern world, with an entire operating system running on a sanctioned-off part of your system. But SheepShaver does allow you to run software written for MacOS 7.5.2 thru 9.0.4 in a different environment. Unix and Linux are both supported, as well as Mac OS X, Windows NT, 2000, and XP, and the enigmatic BeOS. Certain configurations allow applications to run natively without any emulation at all, and there is plenty of hardware support built-in as well.
For anyone running retro hardware from the late 90s or early 00s, this could be just the ticket to get an application running that wasn’t ever supported on one of these machines. As for the name, it’s a play on another piece of software called ShapeShifter which brought a Mac-II emulator to the Amiga. SheepShaver has been around since the late 90s, too, so we’re surprised that we haven’t featured it before since it is such a powerful tool for cross-platform compatibility for computers of this era. Even if all you are hanging on to is an old BeBox.
In the late 80s and into the 90s, [Cameron Kaiser] aka [ClassicHasClass] was an aspiring journalist, first becoming interested in the career in elementary school and then working on various publications into university. At some point, he started using a piece of software for laying out newspapers called The Newsroom which, he admits, was lacking a lot of tools that would have been modern even for the time, but had an otherwise agreeable price tag thanks to its focus more on home desktop publishing and newsletter production than on full-scale newspaper operations. It did have one interesting feature that he never could figure out, though, at least until he went back and pieced this mystery together.
The software itself ran on the Apple II and was eventually ported to other systems of the era, including the Commodore 64. The mystery feature was known as “Wire Service” and appeared to be a way that users of the software who had a modem could connect with one another and share news releases, layouts, graphics, and other content created in Newsroom, but in the days where it would have been modern never was able to connect to anything. In fact, it was eventually abandoned by the developers themselves in later releases of the software. But [ClassicHasClass] was determined to get it working.

Playing classic games, whether they are games from the golden age of arcades or simply games from consoles that are long out of production, tends to exist on a spectrum. At one end is grabbing a game’s ROM file, finding an emulator, and kludging together some controls on a keyboard and mouse with your average PC. At the other is meticulously restoring classic hardware for the “true” feel of what the game would have felt like when it was new. Towards the latter end is emulating the hardware with an FPGA which the open-source MiSTer project attempts to do. This build, though, adds ATX capabilities for the retrocomputing platform.

Everyone knows we’re big fans of displays that differ from the plain old flat-panel LCDs that seem to adorn most devices these days. It’s a bit boring when the front panel of your widget is the same thing you stare at hour after hour while using your phone. Give us the chunky, blocky goodness of a vacuum fluorescent display (VFD) any day of the week for visual interest and retro appeal.
From the video below, it seems like [Posy] certainly is in the VFD fandom too, rolling out as he does example after example of unique and complicated displays, mostly from audio equipment that had its heyday in the 1990s. In some ways, the video is just a love letter to the VFD, and that’s just fine with us. But the teardowns do provide some insights into how VFDs work, as well as suggest ways to tweak the overall look of a VFD.
For example, consider the classy white VFDs that graced a lot of home audio gear back in the day. It turns out, the phosphors used in those displays weren’t white, but closer to the blue-green color that VFDs are often associated with. But put a pink filter between the display and the world, and suddenly those turquoise phosphors look white. [Posy] does a lot of fiddling with the stock filters to change the look of his VFDs, some to good effect, others less so.
As for the internals of VFDs, [Posy]’s look at a damaged display reveals a lot about how they work. With a loose scrap of conductor shorting one of the cathodes inside the tube, the damaged VFD isn’t much to look at, and is beyond reasonable repair, but it’s kind of cool to examine the spring mechanisms that take up slack as the cathodes heat up and expand.
Thanks to [Posy] for this heartfelt look into the VFDs of yesterday. If you need more about how VFDs work, we’ve covered that before, too.

A quick glance at the “Pi Terminal” built by [Salim Benbouziyane], and you might think he pulled an old CRT monitor out of a video editing bay and gutted it. Which, of course, is the point. But what you’re actually looking at is a completely new construction, featuring a fully 3D printed enclosure, a clever PCB control panel, and some very slick internal engineering.
[Salim] started the design by recreating the principle components of the build, namely the 8 inch 4:3 IPS LCD panel and Raspberry Pi 4, digitally in CAD. This let him design the enclosure around the parts, rather than trying to cram everything in after the fact. After printing the case, which clearly took considerable inspiration from broadcast video monitors of the early 2000s, he then painstakingly post-processed the parts using tips and techniques picked up from prop builders. To really finish things off, he designed his control panel as a PCB so he could have it professionally fabricated, and used heat set inserts to hold everything tight.

The Multiple Arcade Machine Emulator, now known simply as MAME, started off as a project to emulate various arcade games. The project is still adding new games to its library, but the framework around MAME makes it capable of emulating pretty much any older computer. The computer doesn’t even need to be a gaming-specific machine as the latest batch of retro hardware they’ve added support for is a number of calculators from the 90s and early 00s including a few classics from Texas Instruments.
Since no one is likely to build an arcade cabinet version of a TI-89, all of these retro calculators are instead emulated entirely within a browser. This includes working buttons and functions on an overlay of each of these calculators but also pixel-accurate screen outputs for each of these. The graphing calculators have more of what we would consider a standard computer screen, but even the unique LCDs of some of the more esoteric calculators are accurately replicated as well thanks to the MAME artwork system.
There are a number of calculators implemented under this project with a full list found at this page, and the MAME team has plans to implement more in the future. If you’re looking for something fun to do on a more modern calculator, though, take a look at this build which implements ray tracing on a TI-84 Plus CE.
Thanks to [J. Peterson] for the tip!
The unique look of early desktop computer systems remains popular with a certain segment of geekdom, so it’s no great surprise when we occasionally see a modern hacker or maker unceremoniously chuck 40+ year old electronics from a vintage machine just to reuse its plastic carcass. We try not to pass judgement, but it does sting to see literal museum pieces turned into glorified Raspberry Pi enclosures.
But with a little luck, perhaps the Retro Wedge Computer case designed by [AndyMt] will be able to save a few of those veteran computers from an unnecessary lobotomy. As the name implies, this 3D printable model is designed to resemble “wedge” desktop computers such as the Atari ST, TI-994A, and Commodore 128. But don’t be put off by its considerable size — the model has been chopped up so no piece is larger than what can fit on a fairly standard 230 x 230 mm print bed.
